Lumbar spinal stenosis lying down is better, lying on the lumbar spinal stenosis condition recovery is unfavorable, the reasons are as follows: First, the occurrence of lumbar spinal stenosis, lying position can make the lumbar spine always maintain physiological curvature, and lying on the lumbar vertebrae anterior and posterior physiological curvature changes, thus causing the lumbar spine front and rear muscle load imbalance, muscle rigidity, tension, fatigue is prone to soreness and pain symptoms. Secondly, lying down position can make the lumbar back muscles to get enough rest, and lying on the lumbar muscles continue to tense, lumbar muscle internal anaerobic metabolism increased, causing lumbar muscle pain symptoms. It can be seen that lying down can make the lumbar muscles get rest and relaxation, and lying down is not conducive to alleviate the symptoms of lumbar muscle fatigue.
